Hi,
In order to answer all your questions it is important to know.
1.When are you going to do the test for the army ?
Working on zone 2 is essential to work on your aerobic capacity , to create on the base for all the specific training you need to do for the assessment day and for basic training, but you will need time to build up that capacity.
2. How much time you have available for training and your fitness level ?
That determines how the periodisation is done, and how and when to tackle the specific training you need to do for assessement and basic training.
3. In basic training and advanced , in all the army branches , and in every country, all the work is done walking with a backpack( with combat gear “ready for combat ) and running . Walking is normally a forced march ( full gear and walking fast) or run with light gear.
In my opinion is almost mandatory that if you aren’t a runner , you become one , but work on loaded walkings to adapt to the stress of carrying wheigt and on a running schedule of at least 1 hour per day , 6 day a week .
In terms of strength , first 6 weeks 3 times per week and then reduce to two times. In basic training and advanced course , they will put a lot of stress , physical and mentally , and so, getting that as fit as possible will help you diminish that.
to have more information about the tests and requirements , the best is to contact recruitment and ask for as much as information as possible, talk with other people that attended and passed the recruitment process. With more information about timings and specific demands is more easy to plan and answer the questions more precisely .
Cheers,
